How to lay out a homelab rack
A good layout keeps cables short, heavy gear low and hot gear apart. This order works for most 10 inch and 19 inch racks.
Most mini PCs, Macs, modems and small switches can't go in a rack on their own. When you add one, the planner puts it in a rack mount made to fit that exact device, from 3D Rack Mounts. Gear that already has rack ears goes straight in.
Tap an open slot to choose where the next item goes. Drag an item to move it (on a phone, press and hold first). Tap it to remove it.
A layout that works
- Patch panel at the top, where the house cables come in.
- Switch right under it, so patch cables are a few inches long.
- Gateway or router and the modem next to the switch.
- Computers (mini PCs, Macs, servers) in the middle.
- Storage (NAS) below the computers.
- UPS and power strip at the bottom. They are the heaviest and their cords run to the wall.
Leave room
Leave 1U to 2U free. You will add something, and a gap above a warm device helps it breathe. A blank or vented panel keeps the front tidy.
Weight and heat
Keep heavy gear low so the rack doesn't tip. Mini PCs and NAS boxes run warm, so don't stack them tight with no gap.
Try it before you buy
The planner above opens with an example build. Swap in your own gear: it shows what fits in your rack height, which devices need a mount, and what you still need to buy. Then share the link with anyone helping you.
Questions
- Should the switch go above or below the patch panel?
- Either works. Right below the patch panel is most common because it keeps patch cables short.
- Where does the UPS go?
- At the bottom. It is usually the heaviest item.
- How many U should I leave free?
- One or two. It gives room to grow and space for airflow.

How it works
- Pick a rack. 10" mini racks (DeskPi, GeeekPi, Lab Rax and similar) or a standard 19" rack, at the height you have.
- Add your gear. Search a device to place it. Gear that already has rack ears, like UniFi and Netgear switches, Synology RackStations, UPS units and PDUs, is in the list too and goes in as rack-ready.
- See what's missing. Anything without ears shows as "needs a mount", with a mount you can buy for it.
- Share it. The link holds the whole layout, so a build can be posted, compared or finished later.
